The trio the author decided on 2026-09-20 is now all built: def is CL's defparameter — its initialiser runs on every daemon re-run, unguarded, so an edited initialiser repaints the same storage on C-c C-c plus re-run — defonce (Clojure's name for CL's defvar, per the author) initialises once behind the .init~once. flag, and defconst stays the image. One parse arm reads both forms; the difference is Ast.reinit, carried to Tast.global's grerun. Emit.startup_plan gives a def no guard flag, and Check.check_global lifts every def initialiser — zero and literal included — into global/<n>, so the host's startup reaches it through the function cell and a re-evaluated def swaps it (Session's def_inits; Emit.redefinition declares the cell for a non-sibling target). The old defvar spelling is refused with the rename and both compiling spellings, and every program, test, doc and editor list is swept — except sand.flan, the author's live WIP, whose seven defvar lines are flagged in FIX.org and keep its three dependent tests red on this branch.

;;;; The same claim as dev-trap-free-all.flan over the other allocator trap,

|
;;;; and with nothing on the restart stack.
|
|
;;;;
|
|
;;;; `nowhere` is a zeroed `Allocator` — a `defonce` nobody assigned — and
|
|
;;;; `free-all` on it is the "I released the region" / "I never made one"
|
|
;;;; collapse the runtime refuses to let a program spell the same way. The
|
|
;;;; refusal is a trap with no transfer channel, so it parks rather than
|
|
;;;; resumes, and here there is not even a restart to list: the break loop says
|
|
;;;; so and stands still, which is the whole difference between a session you
|
|
;;;; can fix the program in and a daemon that is gone.
